The `buildnumber` plugin execution generally fails

[dmlloyd]

I get this output on mvn clean install:

...
[INFO] --- buildnumber-maven-plugin:1.4:create (get-scm-revision) @ jboss-threads ---
[WARNING] Cannot get the revision information from the scm repository, proceeding with revision of UNKNOWN :

We probably don't need this at all. Maybe updating jboss-parent would fix it.
